The suspension system on the tractor.
Mounted plows are connected to the tractor by means of a 3-point linkage, which is part of the tractor's hydraulic lift. The suspension system consists of two arms, to which the two lower arms are connected via hangers. At the ends of the lower pull rods there are holes for attaching two pins of the plow stand or other suspended tool., the third point of the linkage is the link eye, which connects to a corresponding point on the tool stand. The other end of the linkage is pivotally connected to the body of the hydraulic jack. This suspension system provides three degrees of freedom in relation to the tractor, i.e.. The plow or other agricultural tool attached to the tractor may, to a limited extent, rotate in three mutually perpendicular planes. The possibility of rotation in a vertical plane parallel to the tractor driving direction is necessary to obtain an even working depth of the implement. If the implement was rigidly connected to the tractor in this plane, the tool would sink deeper when driving up a hill with the front wheels of the tractor, and when going downhill - the working depth would be reduced.
